Add the PCF option DONT_EXPAND_COLORS

[rodarima]

Allows the user to specify the complete palette in the PCF, preventing Paraver from expanding the colors.

Fixes bsc-performance-tools/wxparaver#8

Here is an example PCF with a carefully selected palette that contains no dark colors:

12  { 15, 181,   0}
13  {  0, 235, 234}
14  {  0, 199, 198}
15  {  0, 178, 235}
16  {  0, 152, 200}
17  { 70, 119, 235}
18  { 53,  96, 199}
19  { 70,  73, 235}
20  { 90,   0, 234}
21  { 84,   0, 219}
22  {168,   0, 234}
23  {234,   0, 230}


EVENT_TYPE
0 36         Label
VALUES
1133833770 VeryDark
9770 MaybeDark
31999 31999
32000 32000
32001 32001

And here you can see the comparison when loading a test trace (with increasing values 0, 1, 2, etc.) without and with the new option DONT_EXPAND_COLORS 1, respectively.

You can see that only the colors defined in the PCF appear in the trace.
